Watertown is a city in Middlesex County, Massachusetts, United States. It is part of the Greater Boston area. The population was 31,915 at the 2010 census. Watertown is one of fourteen Massachusetts municipalities that have applied for, and been granted, city forms of government but wish to retain "The town of” in their official names.

Watertown's proximity to Cambridge and Boston, along with its diverse housing stock, good public schools and safe and quiet neighborhoods, make it a desirable community for families with children.

Watertown is made up of six neighborhoods: Bemis, Brigham (Brigham Historic District), Coolidge Square, East Watertown, Watertown Square and the West End.

History

Archeological evidence suggests that Watertown was inhabited for thousands of years before the arrival of settlers from England. Two tribes of Massachusett people, the Pequossette and the Nonantum, had settlements on the banks of the river later called the Charles. The Pequossette built a fishing weir to trap herring at the site of the current Watertown Dam. The annual fish migration, as both alewife and blueback herring swim upstream from their adult home in the sea to spawn in the fresh water where they were hatched, still occurs every spring.

Watertown, first known as Saltonstall Plantation, was one of the earliest of the Massachusetts Bay settlements. It was begun early in 1630 by a group of settlers led by Sir Richard Saltonstall and the Rev. George Phillips and officially incorporated that same year. The alternate spelling "Waterton" is seen in some early documents.

The first buildings were upon land now included within the limits of Cambridge known as Gerry's Landing. For its first quarter century Watertown ranked next to Boston in population and area. Since then its limits have been greatly reduced. Thrice portions have been added to Cambridge, and it has contributed territory to form the new towns of Weston (1712), Waltham (1738), Lincoln (1754) and Belmont (1859). In 1632 the residents of Watertown protested against being compelled to pay a tax for the erection of a stockadefort at Cambridge; this was the first protest in America against taxation without representation and led to the establishment of representative government in the colony. As early as the close of the 17th century Watertown was the chief horse and cattle market in New England and was known for its fertile gardens and fine estates. Here about 1632 was erected the first grist mill in the colony, and in 1662 one of the first woolen mills in America was built here.

From 1832 to 1834 Theodore Parker conducted a private school here and his name is still preserved in the Parker School, though the building no longer operates as a public school.

The Watertown Arsenal operated continuously as a military munitions and research facility from 1816 until 1995, when the Army sold the property, by then known as the Army Materials Technology Laboratory, to the town of Watertown. The Arsenal is notable for being the site of a 1911 strike prompted by the management methods of operations research pioneer Frederick Winslow Taylor (Taylor and 1911 Watertown Arsenal Strike). Taylor's method, which he dubbed "Scientific Management," broke tasks down into smaller components. Workers no longer completed whole items; instead, they were timed using stopwatches as they did small tasks repetitively, as Taylor attempted to find the balance of tasks that resulted in the maximum output from workers. The strike and its causes were controversial enough that they resulted in Congressional hearings in 1911; Congress passed a law in 1915 banning the method in government owned arsenals. Taylor's methods spread widely, influencing such industrialists as Henry Ford, and the idea is one of the underlying inspirations of the factory (assembly) line industrial method. The Watertown Arsenal was the site of a major superfund clean-up in the 1990s, and has now become a center for shopping, dining and the arts, with the opening of several restaurants and a new theatre. The site includes the Arsenal Center for the Arts, a regional arts center that opened in 2005. The Arsenal is now owned by athenahealth. Arsenal Street features two shopping malls across the street from one another, with the Watertown Mall on one side, and The Arsenal Project of Watertown (formerly the Arsenal Mall) on the other.

Shortly after midnight of April 18–19, 2013, the two suspects in the Boston Marathon bombings engaged in a protracted battle with police, in Watertown, involving the use of firearms and explosives. One suspect was critically wounded and later pronounced dead, and the town was completely locked down for hours as police, FBI, and Army National Guard personnel patrolled it, looking for the remaining suspect, who was captured wounded but alive shortly after the lockdown ended on the following evening.
